Fig. B-2: Reverse osmosis principle
In the osmosis process, watery solutions of different concentra-
tions are separated by a semi-permeable membrane. In keeping
with the law of nature, the concentrations try to equalise. On the
side of the higher original concentration, the so-called "osmotic"
pressure is generated.
In case of reverse osmosis, this osmotic pressure is countered
by a higher pressure. The consequence: the process proceeds
in the reverse direction. A particular advantage of the reverse
osmosis technology compared to other water treatment pro-
cesses is the fact that - apart from the removal of dissolved salts
- bacteria, germs and dissolved organic substances are also re-
duced.
